ROLLER-SUPPORTING DEVICE.

Specification of Letters Patent. Patented June 10, 1919,

Application filed February 14, 1919. Serial No. 276,935.

To all whom it may concern Be it known that I, EDWARD J. MCCAULEY, a citizen of theUnited States, residing at a Philadelphia, inthe county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Roller-Supportin g Devices, of which the following isa specification.

1 One object of my invention is to provide improved supporting devices for the re-rolling rollers forprintmg presses; it being well known that re-rolling rollers are employed to re-roll the form-rollers in order to provide an even distribution of the ink on said form-rollers. j r

Prior to my invention various supporting devices have been employed for re-rolling rollers, but said devices were of such nature as to require constant manual adjustment to prevent drag 'ng.

construct my improved supporting devices that the re-rolling rollers will always be held in proper relation to the form rollers; thereby avoiding dragging and insuring an i even distributioniof the ink on saidformrollers.

Anotherobject isto make my invention of a simple and durable construction and so as to permit the quick and'easy insert1on and.

removal of the re-rolling rollers.

These objects, and other advantageous 1 ends which will 'be described hereinafter, I

printing press form-roller carriage having attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a side elevation showing a my invention thereon,

Fig. 2 is a fragmentary section taken on the line 2+2 of Fig. 1, v

Fig. 3 is a section of one of my improved supporting devices and taken on the line 3-3 of Fig. 1,

Fig. 4 is a section taken on theline 4-4 of Fig. 1 and Fig. 5 is an inverted plan view of Fig. 1. Referring to the drawings, 6 represents a formeroller carriage having form-rollers 7 8" and '9 mounted thereon in the usual man 7 support for the brackets 10 and 11 since said sides of the frame 6 are usually made plane,

Each of the brackets 10 and 11 as illustrated in the drawings includes two boxes or casings 14 which are open at their opposite ends and on their outer side surface are provided with cover plates 15. Guide-ways 16 are thus provided in each of the boxes 14, said guide-ways being tapered or wedge shape in cross section as clearly shown in Fig. 2. A bar 17 slidably fits within. the guide-ways 16 of each of the boxes 14 and has a stem 18 which projects outside of the box. 'These stems 18 have collars 19 secured thereto adjacent their outer ends and rings 20 thereon adapted to abut the ends 21 of the respective boxes 14. Coiled springs 22 surround'the stems 18 and are interposed between the respective collars 19 and rings 20. These springs 22 serve to move the bars 17 in the directionof the arrow as as shown in Figs. 1 and 3. The opposite ends of the bars transversely to the axes of the form-rollers 7, 8 and 9. Each ofthe heads 23 has a notch 25 which extends in the direction of the length of the head; each of said notches hav ing a mouth 26 which leads to the outer side surfaces 27 of the respective head 23.

The notches 25 form sockets forthe opposite end terminals 28 and 29 .of axles 30 which support the re-rolling rollers 31. p

I preferably make each of the axles 30 of a piece of light weight metallic tubing 32 having end pieces 33 forced therein and secured by pins 34. Each re-rolling roller 31 is rotatably supported on the axlev 30 as clearly shown in Fig. 4, said axle having collars .35 secured thereto within the rollers 31. The rollers 31 are preferably made of end terminals ofeaeh of the re-r'olling roll ers are mounted within the notches 250i two oppositely disposed heads 23; said heads as previously stated "being; respectlvelypivoted to two of the bars 17. The springs 22 serveto move the re-rollin'g rollers into engage mentwith t'WO of the form-rollers- 1n the manner clearly shown in Fig- 1. o By having the "heads 23 pivoted to -thebars 17,.oppo'site "portions of there rolling; rollersw'vill always engage the adjacent form roll'ers-since the heads 23 are capable ofQsWi-n-ging in eitherdirection. -I-n other words, the ac'tion of the springs: 22 is to pull one o f the re-rolling? rollers Within-*thfi' space between two-of the form-rollers. However, the movingactionof thesprings 22 is-ar-r'est'ed when the re j rolling ro'ller engages the adjacent formthis reason also, my invention is of particus rollers. The tension of the springs 22 can bevaried bymoving the collars-19 longitu dinal'ly upon the stems-18s Each ofthe collars19 is provided 'withaset' serew 38 vs hich serves toadjustabl'y. secure the collar" 19 to the respective stem 18. Therefore it is obvious that by the use of-my invention it is possible to a keep the re rolling. rollers always in engagement with two 'adj acent form-rollers and that any desirable pressure'of said re-rolling. rollers upon: said form-rollers can be secured. v

Each of the heads 23*at its-outer end is provided with oppositely disposed projecting lips 39. These lips 39 can be easily grasped bet-Ween the'fingers when it i'sdesired'to remove oneof the re-rolling: rollers and, by; pulling the heads against the actions of the-springs 22, the re-rollingrollers canbe moved sufliciently far away from the form rollers to permit the end terminals 28 and 29 to belifted from the notches 25 through the mouths or openings-26. .Therefore no tools required either to remove or replace the re-rollingirnllers;

Byconstructing the braekets-10 and 11 as above described they can be attached to anyform of printingpressformu'ollen carriage merely by screwing-the brackets :to the frame of: thecarriageas=-by the screws 13; It istherefore unnecessary to alter or change the construetlon of-a form-roller carriage in order to attachmy inventiontheretoand for lar val-uei bearing p rtions of sai While I have described my invention as taking a particular form, 1t Will be understood that the various parts of my lnventlon inay 'bechanged without departing from the having a form-carriage: and" form inkingrollers mounted on said carriage; at two sprin'gapressed bans slidably" supported on said form-carriage; members: swing-ablyconnecte'd tosaidspring-pfessed bars; and an ink distributing? roller rotatably supported in said swingably connected rnemberswlfereby said ink distributing rollen is pulled into contact with two adj acent form inking rollers; sdbstantia-lly-as describedz 2.
